... at the casing interface when the wellbore experiences a pressure reduction which occurs after a reservoir is depleted. The microannuli that occur from cement sheath debonding have recently been quantified, but for thin sections at discrete depths. This paper quantifies the microannuli that can occur throughout...

Paper presented at the 49th U.S. Rock Mechanics/Geomechanics Symposium, June 28–July 1, 2015
Paper Number: ARMA-2015-294
... Abstract Microannuli that develop along the cement-casing interface have been identified as common leakage pathways in wellbores. We have developed an experimental system that allows laboratory testing of wellbore specimens which are comprised of a cement sheath cast on a steel casing...
